I'm seeing a lot of people who have a very different take away from the WoT stuff than I do. It seems they think that WoT is some arbitrary "credit score" assigned to users by relay operators or client developers, but from how I understand it, the whole point is that each user will be able to setup their own scoring metrics so each user's WoT is unique.
So user A might see a score of 67 for user C, but user B has set different weights so they see 42 for user C.
Of course, in practice a lot of people will just use the default provider set in their client and that could lead to some issues so I think we just need to make sure that new users have a way of easily setting up their own scoring system and make it very clear that the scores they see are not necessarily what others see.
Perhaps it's possible to build a WoT provider into something like @Citrine or if not maybe just its own standalone app that you point your client towards.
